Plain Surf

#285b56
Notes

Plain Surf (#285B56) is a deep teal with an earthy character. It leans grounded and natural, the kind of color that plays well with wood, clay, linen, and warm neutrals. Its HSL profile (174°, 39%, 26%) places it in the balanced band at a dark lightness. It works well as a headline, icon, or deep background in an otherwise light layout, pairing cleanly with cream, bone, and warm neutrals. For a confident two-color system, pair it with its complementary red. For something softer, pull in its analogous neighbors on either side of the wheel.

Etymology

Plain
adjective

Latin planus, flat, level — used as a color modifier since the medieval period for hues that read as undecorated and direct. Plain white, plain blue: moderate saturation, no shift, no surface effect. Sits in the crisp-bucket center, with the implication of restraint rather than absence.

Surf
noun

The white water produced where waves break — bubbles of compressed air carried in shallow water and dispersing as the wave reforms. The color refers to surf retreating across wet sand: a soft, very pale blue-green with the optical brightness of bubble dispersion. Lighter than seafoam, cooler than frost, with the kinetic weight of a color that's never still — every photograph of surf is already obsolete.
